Title:
ELECTRIC AIRCRAFT AND ABNORMALITY DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/218909
Kind Code:
A1
Abstract:
An electric aircraft (1) comprises a plurality of electric propulsion devices (23a, 23c) that impart a propulsive force to the electric aircraft (1). Each of the plurality of electric propulsion devices (23a, 23c) includes a monitoring unit (25a) and a communication device (26a) that monitor the operation states of the electric propulsion devices and send an abnormality signal to a flight controller (60) when an abnormality is detected. The communication device (26a) is configured to send, via at least a power supply line (70a, 70b), the abnormality signal to the flight controller (60) by superimposing same on an electric signal for supplying power that flows through the power supply line (70a, 70b).
